Abstract: ABSTRACT OF THE DISCLOSURE           The present invention discloses a diode bias toning system for use in and with electrophotographic copying machines and the like, and provides a significant improvement over "float-ing" and "hard-wired" toning systems to provide a user with the benefit of self-compensation or self-adjustment sensitometry, while allowing better control of large density percentage images and providing a simple and practical means and method which yield the satisfactory inherent results or advantages of a "hard-wired" system. The employment of a single diode means connected between a development electrode and a high-voltage D.C. power supply, so as to prevent the passage of current between the development elec-trode and the supply means, thereby facilitates the usage of a single high-voltage D.C. power supply to supply both the corona charging and toning biasing functions of an electrophotographic copying machine or system.

Abstract: TITLE OF THE INVENTION:                  VEHICLE WHEEL  ABSTRACT OF THE DISCLOSURE:     A vehicle wheel having a rigid rim on which is mounted a pneumatic tire which essentially comprises rubber or rubber-like synthetic material.  The tire has a single or multi-ply carcass of metal and/or textile strength carriers.  The carcass is anchored in the tire beads by being looped around the bead cores.  The beads of the tire are disposed on rim seating surfaces next to the rim flanges.  The tire wall, in the region of the rim flanges, extends approximately horizontally toward the outside.  To optimize the neutral line of the carcass, the path of the latter, at least in the lower sidewall region at the level of the rim flange, and laterally outwardly therefrom, conforms to the equation of a catenary.

Abstract: Abstract:    The invention relates to method and apparatus for removing extraneous matter from a cooling water system having a tubular heat exchanger such as a condensor. When a pressure difference between upstream and downstream sides of a filter element exceeds a predetermined threshold value set in advance in accordance with the flow rate of the cooling water, a blow-down operation is started to remove the extraneous matter from the outer peripheral surface of the filter element by a circulating flow.  The extraneous matter can be removed at a degree of clogging of the filter element of 50%, irrespective of the flow rate of the cooling water.  The amount of clogging can be sensed accurately and related to the flow rate of the water so that the blow-down operation is effected with the necessary and sufficient frequency; not too often to waste water or too seldom to permit excessive clogging.

Abstract: A B S T R A C T                METHOD AND MEANS FOR DETERMINING THE SUBSURFACE POSITION OF A BLOWING  WELL WITH RESPECT TO A RELIEF WELL      The subsurface position of a blowing well with respect to an adjacent relief well is determined by detecting at a plurality of axially and tangentially spaced locations in the relief well acoustic waves emanating from a subsurface loca-tion in the blowing well. The distance between the wells is calculated on the basis of the difference in times of arrival of the waves at said axially spaced locations. The radial direction of the blowing well relative to the relief well is determined by measuring the acoustic intensity resulting from the waves at each of said tangentially spaced locations.

Abstract: ABSTRACT OF THE DISCLOSURE    A tire casing is provided herein which includes a puncture-sealing layer attached to the inside surface thereof.  The puncture-sealing layer is made of interwoven flexible cords, both the cords and the sealing layer being rubberized.  Because of the flexibility of the interwoven cords and the elasticity of the rubber, once a sharp object pierces the tire casing and the puncture-sealing layer, the rubberized cords will work tightly to bind the sharp object so as to prevent air contained in the tire casing from leaking out.

Abstract: (54) ABSTRACT          The purpose of the process is to remove and to recover metals from their aqueous solution by the extraction process. As extractant is used monoesters of phosponic acid wherein the alkyl group is a phenyl-vinyl group or straight-chained and the ester group is straight-chained. The particular advantage of the process is that the metals can be removed from aqueous solutions to be treated without neutralization of the acid quantity produced during extraction, and this acid solution produced can be circulated e.g. to the stage before the extraction. The process can be used to the removing of metals from the industrial waste waters.

Abstract: A BIPOLAR INVERSION CHANNEL DEVICE          Abstract A new solid state field effect bipolar device provides for high current gain and low input capacitance, while avoiding the "punch-through" effects that limit the downward scaling of conventional bipolar and field effect devices.  The device typically comprises a metallic (e.g. a metal or silicide) emitter, which makes ohmic contact to a semi-insulator; a channel terminal which contacts an inversion layer formed at the interface between the semi-insulator and a semiconductor depletion region; and a collector, which is the semiconductor bulk.  The novel device controls the flow of majority carriers from the emitter into the collector by the biasing action of charge in the inversion channel.  The technique can be utilized in making a transistor, photodetector, thyristor, controlled optical emitter, and other devices.
